suppressed, but the protective effect against high frequency interfer-
ence signals remains.
Take note of the corresponding installation regulations for Ex applica-
tions. In particular, make sure that no potential equalisation currents
flow over the cable screen. In case of grounding on both sides this
can be achieved by the use of a capacitor or a separate potential
equalisation.
5.2 Connection procedure
Proceed as follows:
1. Unscrew the housing cover
2. Loosen compression nut of the cable entry
3. Remove approx. 10 cm (4 in) of the cable mantle, strip approx.
1 cm (0.4 in) of insulation from the ends of the individual wires
4. Insert the cable into the sensor through the cable entry
5. Lift the opening levers of the terminals with a screwdriver (see
following illustration)
6. Insert the wire ends into the open terminals according to the wir-
ing plan
7. Press down the opening levers of the terminals, you will hear the
terminal spring closing
8. Check the hold of the wires in the terminals by lightly pulling on
them
9. Connect the screen to the internal ground terminal, connect the
outer ground terminal to potential equalisation
10. Tighten the compression nut of the cable entry. The seal ring must
completely encircle the cable
11. Screw the housing cover back on
The electrical connection is hence finished.
